DOOR'HINGE s'ror This invention relates to certain new and usefulimprovements in limit stop means which lends itself to use on and inconjunction with either the top or bottom hinge pintle knuckle of aconventional-type unaltered butt hinge and which is readily applicableand removable, can be selectively set to achieve angular movement, onesetting for an 80 adjustment, a second one for a 180 opening adjustment,and which will work equally well on leftor right-swinging doors.

With respect, generally stated, to the state of the art to which thepresent invention relates it can be pointed out at the outset that it isnot new in the field of endeavor herein disclosed to regulate and limitthe opening and closing of a hinged swingably mounted door byincorporating stop means of one type or another in at least one of thecustomarily used butt hinges. As exemplary of the usage of doors topsthe reader may, if desired, examine the doorstep in Madsen US. Pat. No.2,280,655 or, alternatively, the adjustable stop hinge revealed in apatent to Schwartzberg US. Pat. No. 2,990,572. It will be noted inconnection with these prior patented door hinge stops that they arerigid in construction and lacking the desired property of yieldabilitywould loosen and gradually dislodge the leaf-attaching screws orequivalent fasteners.

An object of the present invention is to structurally, functionally andin other practical ways improve upon the above and other known dual-leafstops and, in so doing to advance the art and to provide a feasiblyresilient limit stop which well serves the purposes for which it hasbeen devised and acceptably used.

Briefly the means herein comprehended is characterized by asubstantially C-shaped clip. The clip is of one-piece construction andis such in size and shape that it is adapted to be conformingly fittedover either one of the end knuckles in a manner to coordinate with theknuckle and the hinged marginal edges of the paired leaves. Moreparticularly, the clip embodies a rounded bight portion a median part ofwhich is provided with a lengthwise outwardly projecting rib. This ribis channel-shaped in cross section and constitutes a limit stop or anabutment and functions to provide a desired stop shoulder. The normallyspaced parallel edges of the clip which are diametrically opposite thestop shoulder are provided with spaced parallel radially and outwardlyprojecting liplike flanges. These flanges are of duplicate constructionand have flat faces which are expressly designed and adapted to straddleand contact the coordinating faces of the hinge leaf which is interposedtherebetween. It is within the purview of the invention to supplementthe clip by installing a coiled collar or split ring on the headed endportion of the hinge pintle and wherein the free ends are provided withlaterally directed parallel fingers which are capable of straddling theaforementioned lips or flanges in a manner to strengthen the same and toinsure a yieldable but firmly reliable result.

These together with other objects and advantages which will becomesubsequently apparent reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming a part hereof, whereinlike numerals refer to like parts throughout, and in which:

FIG. 1 is a view in perspective showing the conventional butt hinge withthe upper-headed portion of the pintle withdrawn partly from the hingeknuckles and showing, what is more significant, the aforementionedC-shaped or equivalent resilient clip readied to be dropped down on thepintle for use.

FIG. 2 is a view similar to FIG. 1 and also in perspective and showingthe clip in its installed ready-to-function position.

FIG. 3 is a horizontal sectional view showing the hinge and limit stopmeans set for use in the manner shown.

FIG. 4 is a view similar to FIG. 3 and showing the leaves of the hingespread apart with the door swung open and with an edge portion of theleaf at the left abutting the limit stop shoulder.

FIG. 5 is a fragmentary perspective view based on FIG. 2 and showing theadded optionally usable stabilizing guard.

FIG. 6 is a view with the guard applied but showing only the retainingfingers in section gripping and retaining the flanges in a seemingself-evident manner.

With reference first and particularly to FIGS. 1 and 2, it will beevident that the butt hinge shown is of a conventional type and embodiesa first leaf 8 at the left having spaced, aligned knuckles 10 along thehinging edge 11 and which are related to thecompanion knuckles 12 on theopposed hinging edge 14. The knuckles 12 are integral with theright-hand leaf 16 and both of these are provided with screw holes 18 ofsuitable construction and relative placement. These knuckles as usualaccommodate the pin or shank portion of the pintle 20 whose upper-headedend is denoted at 22.

The attachable and detachable limit stop means is denoted, generallystated, by the numeral 24 and comprises a substantially U-shaped springmetal clip 26 having opposed curvate body portions 28 joined by a bightportion, said bight portion being bent upon itself and having a hollowoutstanding channel-shaped rib 30 which constitutes a limit stopshoulder and also as abutment. The diametrically opposite free endportions of the arcuate body portions of said clip are fashioned intoand provide spaced parallel liplike flanges 32 which are flat faced areyieldingly resilient and which when in position serve to straddle andyieldingly clench opposite flat faces of the hinge leaf 16. The clip isshown ready for installed use in FIG. 1 and is shown in FIG. 2 in itsusable or performing position. The spring or resilient metal of whichthe clip is made permits it to be fitted over the pintle by spreadingthe flanges or, alternatively, the body portion of the clip is ofsufficient diameter that it can be fitted down over the headed end ofthe pintle.

It is believed that by considering FIG. 1 first the construction andmanner of applying the clip 24 in readiness for use will beself-evident, Then, by comparing FIG. 2 therewith it will be evident howthe clip when fitted into place has its split body portion snuglyembracing the upper knuckle 12. When the clip is pressed down into placearound the upper hinge knuckle the liplike flanges 32 embrace oppositesurfaces of the intervening hinge leaf 16. The limit stop rib orshoulder projects at the desired angle and serves to check the angularswinging movement of the hinge leaf 8.

FIGS. 3 and 4 added to FIGS. 1 and 2 simply bring out the manner inwhich the hinge, hinge pintle, and limit stop clip coordinate andfunction in conjunction with a door and an associated doorjamb or frame.

The purpose of FIGS. 5 and 6 is to bring out, as before suggested, theaddition of and optional use of a stabilizing guard. This guard isdesignated in FIG. 5 by the numeral 34. It comprises a split collar orring, and more particularly, one which is fashioned from a length ofstrap metal which is bent upon itself intermediate its ends to providethe collar desired. More specifically, the collar or ring is coiled ortwisted to provide what constitutes a coil spring 36. This resilientspring encircles the pintle and the free end portions are bent down toprovide duplicate flat-faced stabilizing fingers 38. These fingers areof a length and spaced relationship that they are capable of straddlingthe aforementioned lips or flanges 32. Thus by shoving thefinger-equipped collar or ring down from the position shown in FIG. 5 tothat illustrated in FIG. 6 it will be evident that the fingers 38 thenstraddle the flanges and function to stabilize the flanges so that theywill not be unduly spread or distorted and will maintain the desiredresilient accommodating function.

It will be evident from the disclosure that the primary emphasis is onthe one-piece spring steel or equivalent resilient C-shaped clip 24featuring the limit stop shoulder or rib 30 and the outstanding spacedparallel leaf-straddling flanges 32. Nevertheless and where it is deemedby the installer to be desirable the coiled split ring or guard 34 isbrought into play and is merely slipped over the pintle and then forceddown into position so that the fingers 38 perform the reinforcing orstabilizing function illustrated in FIG. 6.

The foregoing is considered as illustrative only of the principles ofthe invention. Further, since numerous modifications and changes willreadily occur to those skilled in the art, it is not desired to limitthe invention to the exact construction and operation shown anddescribed, and accordingly all suitable modifications and equivalentsmay be resorted to falling within the scope of the invention.
